IMPROVEMENT IN WINDOW PROTECTOR AND VENTILATOR.

Specification forming part of Letters Patent No. 216,712, dated June 17,1879; application tiled April 8, 1879.

To all whom it may concern:

Be it known that I, JOHN L. WALTON, of Bolton, in the county of Hindsand State of Mississippi, havein vented a new and Improved WindowProtector and Ventilator, of which the following is a specification.

The object of this invention is to provide an adjustable windowprotector and ventilator capable of being applied to windows of variouswidths.

It consists of a lattice formed of bars pivoted together diagonally, andhaving on the ends pivoted jaws, with stands to support and steady itwhen in the window.

In the accompanying drawings, Figure 1 shows an'elevation of a windowwith the protector and ventilator in position. Fig. 2 is a section ofthe protector and ventilator.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, the protector an d ventilator A is composedof bars a, pivoted together diagonally, so that they will turn freely ontheir pivots.

The pivoted ends of the bars are held between jaws b, which areconnected to plates 0 at right angles. ()1) the top these plates 0 areturned up at right angles to form recesses d, to receive the edge of thebottom rail of the sash, while those on the ends and bottom are flat, toserve as stands and supports.

i 0.11 the window-sill, immediately under the sash, are fastened plates6, with the outer ends turned upat right angles.

The device is applied as follows: The bottom plates care set on theplates 0, with the ends abutting against the upturned ends of plates 0.The end plates are entered into the rabbets in which the sash runs, andthe sash is placed in the recesses 01 in the upper plates, 0, as clearlyshown in Fig. 1. Thus it is held securely in place, the sash in therecesses and the ends of the plates 6 preventing the pro tector andventilator from slipping out. the same time the ends can be pushedsidewise, so as to fold the bars together when it is desired to open itwithout removing it from the window. Owing to its power of extension andcontraction, it can be applied to windows of various widths.

The arrangement will be found to aflord a very efficient protectionagainst entrance from the exterior, and at the same time allowssufficient light and air to enter.

I am aware that it is not new to use a series of bars pivoted to eachother and held in position against the frame by the weight of the windowresting upon their upper ends; but V What I claim is- The combination,with the pivoted bars a, of the jaws 1), plates 0, of which the upperare turned up and the end as well. as bottom ones flat, and the plates0, turned up at the outer ends, as shown and described.
